System Overview
This ventilator provides both pressure control and volume modes of
therapy. The device can provide non-invasive or invasive ventilation.
It can be used to provide total therapy to patients as they progress
from non-invasive to invasive ventilation.
When prescribed, the device provides numerous special features to
help make patient therapy more comfortable. For example, the ramp
function allows you to lower the pressure when trying to fall asleep.
The air pressure will gradually increase until the prescription pressure
is reached. Additionally, the Flex comfort feature provides increased
pressure relief during the expiratory phase of breathing.
The ventilator can be operated using several dierent power
sources, including an internal Lithium-Ion battery. This battery is
automatically used when the detachable Lithium-Ion battery pack,
external Lead Acid battery, or AC power are not available.
